Dosing and dispensing mechanism for sawdust or sealing compound

Abstract

The invention relates to a metering and dispensing mechanism for sawdust or sealing medicine, which comprises a bracket, a silo, a horizontally arranged guide rail, a sliding piece, a pushing cylinder, a metering container and a pneumatic valve. The discharge port of the silo is located at the bottom of the silo, and the discharge port is an elongated opening extending along a horizontal straight line; a blanking scraper is fixed on the silo close to the discharge port, and the extension direction of the blanking scraper is It is parallel to the extension direction of the discharge port; the guide rail is installed on the bracket, and the sliding piece is slidably installed on the guide rail. Pushing the cylinder can push the sliding piece to reciprocate along the guide rail; the metering container is provided with a metering through hole that runs up and down; a pneumatic valve is set close to the bottom of the metering container, and the pneumatic valve controls the opening and closing of the downward conduction path of the metering through hole; The blanking scraper can be in close contact with the upper end face of the measuring container. The invention can automatically complete the work of measuring and sub-packing the wood chips or the sealing medicine, thereby improving the automation degree and safety of fireworks production.

Description

technical field [0001] The invention relates to a process equipment for the production of fireworks inner cylinders, in particular to a metering and packing mechanism for sawdust or sealing medicine. Background technique [0002] In the process of fireworks production, due to technological requirements, it is necessary to pour the propellant (ie, bright beads and unpacking medicine) into the inner tube of the fireworks, and then fill a certain amount of wood chips into the inner tube, and finally fill a certain amount of sealing. medicine to form a finished fireworks inner tube. Propellant is a granular item similar to the size of millet. In the past, drug filling was done manually. The labor intensity of workers was high, and the production efficiency was low. It was easy to waste raw materials and affect product quality. Later, semi-automatic filling devices appeared, but these devices still required manual operation of the filling plate. Each time the filling was done, t...

Problems solved by technology

The propellant is a granular item similar to the size of millet. In the past, the drug filling was done manually. The labor intensity of the workers was high, the production efficiency was low, and it was easy to cause waste of raw materials and affect product quality.

Later, semi-automatic filling devices appeared, but these devices still require manual operation of the filling board, and each time the filling is done, the blocking board is pulled once. Repeated work requires a lot of physical strength, and workers are exposed to drugs for a long time, which is harmful to their health. There is a great impact, exposure to flammable and explosive dangerous drugs at work, threatening personal safety
